Negative ion ceramic glaze and method for preparation of negative ion ceramic brick from negative ion ceramic glaze

The invention relates to a negative ion ceramic glaze and a method for preparation of a negative ion ceramic brick from the negative ion ceramic glaze, and belongs to the ceramic processing technical field. The negative ion ceramic glaze comprises the following components: kaolin, potassium feldspar, nano titanium dioxide, nano tourmaline powder, nano lithium tourmaline powder, nano magnesium tourmaline powder, praseodymium oxide and water. The above materials are filled into a ball mill for ball milling for 12-58 h, the negative ion ceramic glaze is obtained by deironing and sieving processes, a dried ceramic body is applied with the negative ion ceramic glaze in glaze spraying manner, the glaze thickness is 0.35-0.35 mm, and a negative ion glaze brick with health care and environmental protection functions can be obtained by firing for 2-8 h at 1000-1280 DEG C. The negative ion glaze brick can release negative ions to increase indoor air negative ion concentration, improve sleep, smooth respiration, enhance immunity, normalize blood pressure, purify blood, and so on.
